Sadly that patch never made it to the mainline
It seems to me the only reason the patch did not go to the mainline was to understand who should merge it and then push to Wolfgang.
Usually I take small changes to the other subsystems with an ACK from the maintainer and I merge it myself. The series in question was part of a set of I believe 9 patches which made quite a few changes to the MMC subsystem.
I asked the author to resubmit patches quite a few times but have not received a response. If anybody can do the rebasing and testing that would be welcome.
Probably what we need is to check again the status of this patch. I cannot find it on patchwork, it looks like it was missed ;-(.
I see a patch to enable USB in da850evm, too::
